Liquid crystal molecules form nano rings

At DESY's X-ray source PETRA III, scientists have investigated an intriguing form of self-assembly in liquid crystals: When the liquid crystals are filled into cylindrical nanopores and heated, their molecules form ordered rings as they cool—a condition that otherwise does not occur naturally in the material. This behavior enables nanomaterials with new optical and electrical properties, as the team led by Patrick Huber from Hamburg University of Technology (TUHH) reports in the journal Physical Review Letters.

Theoretical physicists manipulate light with nanoscale objects

For years, scientists have long wrestled with the control and manipulation of light, a long-standing scientific ambition with major implications for the development of technology. With the growth in nanophotonics, scientists are making gains faster than ever exploiting structures with dimensions comparable to the wavelength of light.

Researchers demonstrate graphene as a source of high-speed light pulses

One of the key requirements of future optical communications technologies is a nanoscale light source capable of emitting ultrafast light pulses. In a new study, researchers have shown that graphene may be an ideal candidate for such a light source, by demonstrating graphene-based devices that emit light pulses with a bandwidth of up to 10 GHz and pulse durations of less than 100 picoseconds (or 10 billion pulses per second).

Measuring the temperature of two-dimensional materials at the atomic level

Researchers at the University of Illinois at Chicago describe a new technique for precisely measuring the temperature and behavior of new two-dimensional materials that will allow engineers to design smaller and faster microprocessors. Their findings are reported in the journal Physical Review Letters.

Building miniature optical antennas using DNA as a guide

An international research collaborative has reported a new, highly parallel technique to fabricate precise metallic nanostructures with designed plasmonic properties by means of self-assembled DNA origami shapes. The so-called DALI (DNA-assisted lithography) method has been published in the latest issue of Science Advances.

Creating an electron-hole liquid at room temperature

Making a liquid out of electrons is complicated, but it opens the door to research in a wide variety of electronics. NC State physicists have created a phase diagram that can help researchers create this liquid at room temperature, making it much easier for everyone to study.

Researchers developing 2-D materials similar to graphene

Chemists are working to synthesize the next generation of super materials for high-performance electronics, solar cells, photodetectors and quantum computers. While they have made progress with compound materials, they have not yet succeeded in developing unaltered or "freestanding" materials for such devices, according to a review published in the journal Science and Technology of Advanced Materials.

New, safe zinc oxide quantum dots

Nowadays, zinc oxide nanoparticles are among the most commonly used nanomaterials. They seem to be safe for humans, but there are still no standards for their toxicity, and despite investigations, the toxicological impact of ZnO nanomaterials remains ambiguous. Researchers from the Polish Academy of Sciences (IPC PAS) in Warsaw and the Warsaw University of Technology (PW) have recently developed a method for producing defect-free ZnO quantum dots with enduring physicochemical properties such as monodispersity, a relatively high quantum efficiency, record-long luminescence lifetimes and EPR silence under standard conditions. The tightly coordinated and impermeable organic shells that stabilize the surface make the new ZnO quantum dots resistant to both chemical and biological environments.

A biological approach to precision medicine targets endless number of diseases

The biological complexity of cancer and other diseases demands a more formidable arsenal of therapies than currently available. Most therapeutic approaches ignore the dynamic molecular network of genes, targeting instead only very few selected disease-related genes.

MXene material could improve sensors that sniff

Sensors that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person's breath. Researchers from Drexel University and the Korea Advanced Institute of Science and Technology have made a discovery that could make our best "chemical noses" even more sensitive.

Self-assembled 'hairy' nanoparticles could give a double punch to cancer

"Hairy" nanoparticles made with light-sensitive materials that assemble themselves could one day become "nano-carriers" providing doctors a new way to simultaneously introduce both therapeutic drugs and cancer-fighting heat into tumors. That's one potential application for a new technology that combines water-repelling yet light-sensitive and water-absorbing materials into polymeric nano-reactors for creating photo-responsive gold nanoparticles.

Skin-inspired coating that's as hard as teeth and can heal itself

Self-healing smart coatings could someday make scratches on cell phones a thing of the past. But researchers often have to compromise between strength and the ability to self-repair when developing these materials. Now, one group reports in ACS Nano the development of a smart coating that is as hard as tooth enamel on the outside but can heal itself like skin can.
